i have a 2000 400EX with an FMF powercore 4 silencer, stage 1 hotcam, stock gearing, and except for the cam, a stock engine. i'm looking for the best, and cheapest engine mod available. i want power, and speed. i don't want my quad to be fast and not be able to climb hills. i also want to be able to run my quad off of pump gas, right now i use 91 octane. what r my options?
